Embodiment
Fig. 1 is a) traditional single phase bridge rectifier line assumption diagram, Fig. 1 b) be the voltage oscillogram before and after rectification.Rectifier is the rectifier bridge be made up of four diode (rectifying tube) D1 ~ D4, forms four ports, and middle two ports pass into one-way communication electricity, and two top ports are respectively galvanic positive and negative terminal and export.If by a sinusoidal voltage Ua input rectifier AC port, be just equivalent to become galvanic positive half cycle by rectifying tube by after the reversion of the negative half period of alternating current, waveform is shown in the Ud curve of bottom righthand side.If there is no filtering capacitor, then in the DC voltage waveform exported, Ud is from most significant end voltage to no-voltage, voltage difference between peak valley is very large, that is Ud has a very large breach, AC ripple value contained by direct current is very large, only have with very large electrolytic capacitor just can make containing AC ripple so large direct current meet stable power-supplying application requirement, so its filtering loss is also very large, electrolytic capacitor is easy to heating, and the reflection of this rectifier power source filtering electric energy loss just of generating heat.
Fig. 2 is low ripple rectifier Structural drawing of the present invention and rectified waveform figure.In Fig. 2 circuit a), add phase-shift circuit (2), new rectifier (1) is formed with two rectifying tube D5 and D6 increased and original four rectifying tubes, D1 ~ D4 and Fig. 1 is identical, a phase shifting capacitor C and two rectifying tube D5 and D6 that the present invention increases constitutes another rectification branch road in parallel, be equivalent to D5 and the D6 branch road will sent into after alternating voltage phase shift in rectifier by C, and the alternating voltage after phase shift is just located in the paddy district of original DC voltage waveform after rectification, if capacitance is suitable, suitable great Yi Kuaigu district can be made to be filled up, the result of such compound, paddy district area greatly reduces, its Ud envelope presents more smooth waveform, ripple reduces greatly.Fig. 2 b) be low ripple rectifier rectification oscillogram of the present invention, in figure, entity part is exactly the voltage increased, visible, the feature of low ripple rectifier is, single phase power supply, have phase-shift circuit (2) before rectifier, rectifier increases D5 and D6 branch road, and the alternating voltage after phase shift just falls into the paddy district of original DC voltage waveform after rectification.Not only low ripple rectifier waveform is good, and average voltage is also high than traditional single phase rectifier.Adopt low ripple rectifier, just do not need with very large filter capacitor, certain filtering loss will greatly reduce, and this is the large reason producing energy-saving effect.
The numerical value of phase shifting capacitor C needs the size according to DC load current and determines, and to make the effect of phase shift best, ripple is minimum.
In the present invention, although add a phase shifting capacitor and two rectifying tubes, cost can increase to some extent, but the capacity of filtering capacitor can reduce greatly, so appropriate design just can make low ripple rectifier cost be unlikely to increase, if consider energy-conservation economic worth this part, so economize on electricity equals the operating cost of reduction equipment, calculates especially economically.
Fig. 3 is the low ripple rectifier Structural drawing replacing electric capacity phase shift with inductance.The loss ratio electric capacity of inductor is bigger, cost also ratio capacitance is high, but the secondary control system work responding to a small-power low-voltage (being equivalent to the secondary of small transformers) power supply source device of inductor, because the power of shunting is minimum, so the function of inductor is substantially constant, this is that it is better than the important advantage of capacitor.
Fig. 4 is the voltage phasor-diagram of the accurate three-phase rectifier of single phase power supply after desirable phase shift.For fixing DC load current, select suitable amount of phase shift, the voltage obtained by phase shift is made to be in B point position in alternating voltage phasor diagram, so probably form an equilateral triangle ABC with original voltage AC 2, at this moment, can think that the present invention is by phase shift, in fact its feature is equal to single-phase electricity is turned into three-phase electricity, in fact low ripple rectifier has changed over three-phase rectifier, and the DC waveform after its rectification is the higher harmonics frequency of 6 pulse waves.Single-phase electricity by the feature of the accurate three-phase rectifier formed after phase shift is, phase shift electricity forms with former single-phase voltage the three-phase electricity that is as the criterion, i.e. Uab=Ubc=Uac=Ua, rectifier becomes three-phase rectifier.
It should be noted that, the accurate three-phase rectifier of single-phase electricity by being formed after phase shift, under the prerequisite that components and parts capacity is determined, only just set up at a certain POL determined, after load changes, components and parts capacity must change thereupon, three-phase symmetrical could be maintained, otherwise two voltage values in three voltages can change.Even if but be not three-phase symmetrical completely, compared with two multiplied frequency harmonic of single-phase bridge, harmonic content has the range of decrease of matter, and filtering is also easier, and energy-saving effect is better.
As can be seen from Figure 4, two terminal A of single-phase voltage Ua originally and C, and from the voltage terminal B after Ua phase shift, 3 three-phase voltages being equivalent to delta connection, that low ripple rectifier below also just becomes a tool three-phase rectifier naturally.
For the detailed description of low ripple single-phase rectifier, visible Chinese patent office file 201310331608.8.
Above content is low ripple rectifier part of the present invention, and low ripple rectifier is powered by single-phase alternating current, and the normal voltage of application is usually the interchange networking of 220V, and power is less.For safety, single phase poaer supply input can increase isolating transformer, and the high frequency transformer of the DC chopped-wave first after low ripple rectifier also can be adopted to do to isolate.
Introduce virtual six-phase rectifier of the present invention below, virtual six-phase rectifier is mainly used in the continuous-current plant of three-phase electricity input.
So-called virtual six-phase rectifier, because inventor is when the energy-conservation large problem of research electrical network, first found " the line loss of voltage in three-phase electricity system ", and adopt six-phase rectifier commutating voltage can be raised the multiplying power of 15.6%, make that rectifying installation improves than traditional three-phase rectifier capacity, efficiency rises.But existing electrical network unification becomes the three phase supply net in the whole world, without six phase electricity supplies, so six-phase rectifier cannot adopt.Virtual six-phase rectifier is exactly that one can adopt three phase supply, but the new rectifier topological structure that its efficiency is equally high with six-phase rectifier again, because be not real six-phase rectifier, but its principle interosculates with six-phase rectifier again, therefore named virtual six-phase rectifier.Virtual six-phase rectifier effectively can overcome the line loss of voltage in three-phase electricity system, and its know-why as shown in Figure 5.
Fig. 5 is virtual six-phase rectifier Structural drawing of the present invention and phasor diagram.The feature of virtual six-phase rectifier is: rectifier (1) is made up of three parallel branches, parallel branch is in series aiding connection by two pole device D1 and D4, D2 and D5, D3 and D6 respectively, and the mid point of two diodes of connecting in every bar parallel branch connects the output phase line of three-phase alternating-current supply (4); In rectifier (1), the negative terminal that connects altogether of two pole device D1-D3 is galvanic positive pole, and the anode that connects altogether of two pole device D4-D6 is galvanic negative pole; Filter capacitor (3) is in series by capacitor C1 and C2 of equal capacity, and the mid point of C1 and C2 receives the zero line of three-phase alternating-current supply (4), and the other end of C1 and C2 connects galvanic both positive and negative polarity respectively.The topological structure of virtual six-phase rectifier is shown in Fig. 5 a).
Fig. 5 b) be three-phase alternating voltage phasor diagram.The essence of virtual six-phase rectifier is exactly " separation " by rectifier, utilizes-Ua ,-Ub after phasor Ua, Ub, Uc paraphase, symmetry six phase that-Uc obtains jointly, point arranges rectifying tube rectification respectively up and down, and the direct current then synthesized exports.
So-called " the line loss of voltage in three-phase electricity system ", its brief principle is, supposes that the phase voltage of generator G is 220V, star connection, by three phase lines, voltage is accessed the input of bridge rectifier, and that in fact utilize is the line voltage 380V of alternating current.Rectifier bridge carries out rectifying conversion to the line voltage of 380V just, could obtain direct current and export, so the line voltage positive correlation of its output dc voltage and 380V.
Fig. 6 and Figure 7 shows that four phases, five phases, six phases and seven cross streams voltage vector-diagrams.Same 220V phase voltage, the ceiling for accumulation voltage 418V of five phase alternating currents, the ceiling for accumulation voltage of seven phase alternating currents is more up to 429V, and the ceiling for accumulation voltage of four phases and six phases is two times of 220V phase voltage, i.e. 440V.Can very intuitive and convenient compare from figure they quantitatively with the difference of three-phase wire voltage, although the AC power that is obtained under same generator mesostructure when them is identical, but the direct voltage exported after being through rectifier and power, polyphase system is all obviously greater than three-phase electricity system.
About virtual six-phase rectifier more detailed description, refer to Chinese patent office file 201310381920.8, do not repeat herein.
The efficiency of virtual six-phase rectifier, through user and authoritative test agency checking, really has the advantage higher than traditional three-phase bridge rectifier, virtual six-phase rectifier is used for the continuous-current plant of three-phase electricity input, has obvious energy-saving effect.
For improving power factor, reducing rectifier loss, the single-phase rectifier in the present invention, three-phase rectifier or virtual six-phase rectifier can be uncontrollable rectifier, can be PWM rectifications, to improve power factor, reduce line loss; In order to regulate direct voltage, phase control rectifier or PWM rectification also can be adopted; Rectifying tube can be silicon diode, also can be metal-oxide-semiconductor or IGBT pipe.Rectifier efficiency and rectifying tube in close relations, rectifier loss mainly contains rectifying tube the forward voltage drop heating loss produced and the loss that commutates, the forward voltage drop of silicon diode is usually at 0.6 ~ 1.6V, ge rectifying transistor, Schottky Rectifier are about 0.4V, and the forward voltage drop of transistor, metal-oxide-semiconductor or IGBT pipe even may lower than 0.1V.The measure reducing rectifying tube commutation loss is the rectifying tube that employing switching tube or fast recovery diode, particularly switching frequency are higher.
Adopt the virtual six-phase rectifier continuous-current plant of three-phase electricity input, although have obvious energy-saving effect, power is also apparently higher than single-phase low ripple rectifier DC supply unit.But, in the face of the DC load that capacity is larger, virtual six-phase rectifier can inject a large amount of harmonic wave to electrical network when exporting high power DC electricity, make alternating voltage waveform Severe distortion, thus while pollution electrical network, a large amount of harmonic loss is produced, so in the very large direct current supply place of power consumption, such as electrolytic aluminium factory, direct current electric arc furnace or subway traction power supply station, must be equipped with rectifier transformer in commutation supply voltage institute.
Be not difficult to find from the analysis of upper joint, the line loss of voltage of heterogeneous electricity is little, is conducive to improving rectification efficiency, and also few to the harmonic content of electrical network injection after heterogeneous electric rectification, so multi-pulse rectification transformer also becomes the pith of DC rectification power device.The essence object adopting multi-pulse rectification transformer is that three-phase electricity is upgraded to heterogeneous electricity.
The present invention for the technical characteristic of significant power DC rectification power device is, adopts rotating magnetic field polyphase transformer to replace multi-pulse rectification transformer.
Fig. 8 is the overall structure schematic diagram of rotating magnetic field polyphase transformer of the present invention.In fig. 8, the former limit (51) of three phase transformation polyphase transformers is equivalent to the rotor of wound induction motor, is inlaid with the winding of three-phase star or delta connection above.Difference is that transformer does not need axle, does not also need the iron core near axle place, as long as and a ring bodies yoke just can complete magnetic loop.The former limit of rotating magnetic field polyphase transformer embeds the armature winding of three-phase structure, the rotating magnetic field direction produced by armature winding is radial, and in ring as clock rotational flow, at radial rotating, this magnetic field is completely different from the magnetic direction of the toroidal transformer that market is widely applied, the latter is all along the circumferential direction flowed in magnetic field in ring, is only suitable for single-phase electricity transformation.And the rotor in the winding of rotating magnetic field polyphase transformer and magnetic structure and asynchronous winding motor is basically identical, principle is also identical.
The secondary (52) of rotating magnetic field polyphase transformer embeds the N phase secondary winding of heterogeneous structure, and N is any positive integer, is equivalent to the stator in asynchronous winding motor.Secondary winding is by common magnetic circuit (53) and armature winding close coupling, secondary winding is also radial distribution, and be coupled with the tight interlinkage of armature winding via the rotating magnetic field in common magnetic circuit (53), a ring bodies yoke is retained, to keep magnetic line of force path in secondary winding outer end.Stator armature winding in its structure and principle and asynchronous winding motor and magnetic circuit are also basically identical, and difference is, the stator armature winding in motor is three-phase structure, and secondary winding alleged in transformer of the present invention designs by heterogeneous structure.
Layout in Fig. 8 is, at interior, secondary winding outside, but the position of armature winding and secondary winding can exchange armature winding, and make secondary winding at interior and armature winding outside, this is just more close with the input/output relation of wire-wound asynchronous motor.
Fig. 9 is the overall line assumption diagram of rotating magnetic field polyphase transformer.In the outside wire casing on the iron yoke face of cylinder, inner side of rotating magnetic field polyphase transformer, be inlaid with three-phase former limit winding (51), and be inlaid with heterogeneous vice-side winding (52) in the inner side wire casing on the iron yoke face of cylinder, outside of rotating magnetic field polyphase transformer.Heterogeneous vice-side winding is n phase, namely has n group winding.Diagram magnetic structure is the rotating magnetic field that number of pole-pairs p equals 1, and its feature is to hold more phase, and shortcoming is that magnetic circuit is longer; Along with the increase of number of pole-pairs p, the corresponding shortening of magnetic circuit, but not easily obtain the more number of phases, so p generally can not more than 4.As can be seen from the figure, the overall structure of rotating magnetic field polyphase transformer is equivalent to wire-wound asynchronous motor substantially.
Employing rotating magnetic field polyphase transformer as the advantage of the continuous-current plant of rectifier transformer is:
1, do not need the air gap needed for motor between rotating magnetic field polyphase transformer primary and secondary, the magnetic coupling between primary and secondary winding is tightr, and magnetic resistance, leakage field are less, and therefore required exciting current is quite also little more than motor with common transformer.
2, rotating magnetic field polyphase transformer is secondary can be the n phase polyphase windings that annular connects, and also can be the n phase polyphase windings of star structure.The winding utilization of ring connection is high, effective.
3, in existing heterogeneous (pulse wave) rectifier transformer, number of phases n must be the multiple of 3, but in rotating magnetic field polyphase transformer of the present invention, n can be any positive integer, both can be odd number, also can be even number, need not to be the multiple of 3, the effect of odd number is better.
4, due to the symmetry of motor winding construction, the phase voltage symmetry of rotating magnetic field polyphase transformer and consistency are better than multi-pulse rectification transformer, the each alternate difference between winding and magnetic circuit of the many pulse wave transformers of similar existing tradition is there is not between each phase, harmonic wave after rectification particularly low-order harmonic amount will obviously reduce, line voltage current waveform is closer to pure sine wave, and the electromagnetic pollution of electrical network will obviously reduce.
5, along with the increase of pulse number, multiple stage multi-pulse rectification transformer must be adopted, and rotating magnetic field polyphase transformer one enough, so adopt rotating magnetic field polyphase transformer can reduce the trouble of many pulse wave transformers wiring, reduce the cost of system.
6, rotating magnetic field polyphase transformer can adopt zero clearance magnetic circuit technology and reduce the excitation loss of transformer further.
Detailed technology about rotating magnetic field polyphase transformer describes visible Chinese patent office file ZL201320201736.6 " the efficient electrical equipment that poor efficiency motor is changed system into ".
In order to keep the symmetry of winding, rotating magnetic field polyphase transformer adopts the mounting structure form of central axis usually, phase with vertical installation is also beneficial to and adopts air-cooled or oil cooling radiator structure, in air-cooled structure, air blast be in transformer lower end and to up-draught, between winding and be all designed with the air duct of vertical direction between iron core, make each heat radiation mutually evenly.
In oil cooling structure, then with the copper tube sections of hollow or all can form winding, and unshakable in one's determination employing there are the step-by-step arrangement of interval location and the oilhole of vertical direction, are beneficial to the flowing heat radiation of cold oil.
Figure 10 is the DC bus powered power supply architecture block diagram of the superpower of employing rotating magnetic field polyphase transformer of the present invention.In Fig. 10; the electric power of three phase network is introduced rotating magnetic field polyphase transformer (5); obtain the output of n cross streams and be connected to rectifier (1); certainly; rectifier in this example is polyphase rectifier; more level and smooth high power DC electricity input direct-current bus is obtained by polyphase rectifier; by DC bus, DC high-power input dc power switchboard or switch protection are shielded (6), to supply the DC current flow required for independent heavy load or different collectives branching unit.
